Summary of Clinical Use
This drug is an atypical antipsychotic used to treat psychosis in schizophrenia and manic episodes of bipolar disorder. However, there is no information regarding approval for use of this drug for these indications on the US FDA or European Medicines Agency websites. Other national approval agencies may have granted marketing authorisation for use in these conditions.

In February 2020 the FDA granted approval for amisulpride injection (Barhemsys) to be used to help prevent postoperative nausea and vomiting.
Amisulpride causes dose- and concentration-dependent QT prolongation, so caution is advised for patients with pre-existing medical conditions or who are taking other medications, that are known to prolong the QT interval. Avoid use of amisulpride in patients with congenital long QT syndrome or who are taking droperidol.
Mechanism Of Action and Pharmacodynamic Effects
Amisulpride is primarily an antagonist of the dopamine D2 and D3 receptors.
